Savoy, P., and Harvey, J.W., 2021, Light model and GPP estimates for 173 U.S. rivers: U.S. Geological Survey data release, https://doi.org/10.5066/P9LREC3P.

Summary

This data release contains products from Savoy & Harvey (2021) which modeled photosynthetically active radiation and gross primary productivity (GPP) for 173 streams and rivers across the continental United States. Estimates of photosynthetically active radiation (PAR) were generated using a model that considers the contribution of light attenuation from riparian zones as well as within the water column. PAR estimates at the stream surface and within the water are both provided and each of these two estimates were converted to GPP estimates using a fixed light use efficiency. This data release includes the site parameters, model inputs, model outputs, and model source code use to generate these estimates. Items in this data release [...]

Purpose

Light mediates a number of stream ecological processes and the ability to quantify light environments experienced by stream organisms can facilitate better understanding of the role light plays in mediating these processes. This data release provides estimates of light and gross primary productivity for 173 streams and rivers across the continental United States.
